To all 107mm t may concern.' Y Beit known that I, RICHARD W. BURNETT, States, residing at Chicago, in the countyV of YCookand State of linois, have invented a certain new and Coupling Release- Rigging, of which the following is a full. clear,- concise, and exact description, referyence being had ,to the accompanying drawings, forming a part of this speciication. This invention relates to improvements in coupler release rigging. Y Objects of this invention are to provide a release rigging for couplers which is composed of a minimum number of parts; which permits of a wide range of .iiexibility in the lateral and longitudinal movements of the coupler; and which is so arranged that the il ustrating one embodiment of my inven- Fig. 2 is a vertical, sectional view, taken longitudinally of the car and at one side of the coupler. Fig. 3 is an end elevational view showing more particularly the eonnectinglink between the coupler lock and uncoupling rod and the manner of at-tachinent of said link to said other two members. And Fig. 4 is a detail horizontal sectional view taken substantially on the line 4`4 of Fig. 2.

In said drawing, 10 denotes the end sill of a. freight car, 1l the buii'er block or casting and 12 the coupler head provided as usual with the pivoted knuckle 13. he coupler is also provided with a coupler lock 14 of a well known form having an eye 15 at its upper end. A designates the uncoupling rod or lever, the same having zontal portion 17 parallel of the car, an outwardly and downwardly extending arm 18 located over the coupler head, said arm 18 at its outer end bein provided with a substantially horizontally eX- tending portion 19 arranged transversely to with the end wall Specification of Letters Patent.

a Yhandle 16, horithe longitudinal center line of the car, said member 19 being provided with an end 20 which is bent so as to extend backwardly toward the end of the'car and inclined downwardly from the horizontal when .the

-hnk B, as shown, is provided at its lower end with an eye 23, the plane of which is normally parallel with the 'en'dfwall of the car, said eye being linked with the eye 15 of the coupler lock. Above the eye 23, the link B is provided with an elongated slot 24 within Which is normally received the horizontal portion 19 of the uncoupling rod, the latter being adapted to work up and down in said slot 24, as will be apparent. As pears from Figs. 3 and 4, the front or outer portion 25 of the link B is narrower than the widened flat back 26, or, stated in another manner, the general in horizontal section where it is engaged by the uncoupling rod is triangular for the purpose hereinafter specified.

n assembling the release rigging, the link B is first attached to the coupler lock 14 in t e manner shown, after which the hook shaped inner end of the uncoupling rod A is threaded through the slot 24 of the link Finally the uncoupling rod A is attached to the car end by. the brackets 21 and 22. After the parts are assembled, it will be obvious that the link B cannot slip accidentally around the corner or bend 27 in thel uncoupling rod A, which is between the por` he wide back 26 of nection between Patented N ov. 5V, 1918.

contour of the link B L possible due to the con- Furthermore, the lever arm 18 of the rod A is so disposed as to obtain maximum leverage in lifting the coupler lock. It Will also be observed that the rod A may be formed readily and cheaply from ordinary stock by simple bending operation to the desired form and also that the link B may be readily and cheaply manufactured.

I have herein shown and described what I no w consider the preferred embodiment of my invention but the same is merely illustrative, and I contemplate all changes and modifications that come within the scope of 'the claims appended hereto.

I claim:

1. In a coupler release rigging, the combination with an uncoupling rod having a substantially hook shaped end at its inner end adjacent the coupler, of a slotted connecting link adapted to operatively connect said lever with a coupler lock, said rod eX- tending through the slot in said link and said link hein g Wider on one side of the slot than on the other to thereby prevent the link five cents each,

from passing accidentally around bends in said uncouplmg rod.

2. In a coupler release rigging, the combination with an uncoupling rod and a coupler lock having an eye at its upper end, of an intermediate connecting link between said rod and lock said link having an eye at its lower end linked with the eye of said lock and slotted at its upper end, a portion of the uncoupling rod being extended through said slot and slidable therevvithin, the uncoupling rod being provided with shouldered portions therein at opposite sides of the link, and means preventing accidental disengagement of said link from the rod when the link and rod are assembled, said means including a widened back wall on the link preventing the link from accidentally passing around said shouldered portions of the rod.

In Witness have hereunto subscribed my name day of January, 1916.

RICHARD W. BURNETT.
